OGEN-CONTROLLED LOCK. i

Specification of Letters Patent.

Patented Mar. 16, 1915.

Ee it known that i, En. :L Citizen'oif the United Stati@ resii'ling at Indianapolis, in the eoun: ot irf'iorion and Stte of indiane, have inve-ded u new and useful Coin-Controlled Loek, oil: which the following is n spefzicetioin It is the object of n.134' invention to provide a eoin-controlled oolr which can he operated from one side only; oy dep siting a coin but een he operated jroni other side Without :i Coin which malte-s record oi its Coin-prodnfled operations: which after having olive i V.n operated. hv o coin sonnet again he nlarly operated until otterit has heen operated 'from the other side; which is as thin :is posehle, even thinner than the diameter of the coin; sind which is substantinllv fool-proof and is without exposed parte `which een be tampered with.

The accompanying drawing illustrates my invention Figure 1 a liront elevation of the oom` pleteloelr, with some parts orohen fnv: Fig. 2 is a front elevation of suela lool( with the cover renn:'\.e i, hut with the operating; member carried hf; surh @over shown in place; Fig. 3 is n View similar to Fig. l but showing the holt drawn hoch; und Fig. 4 is a section on the line #nel or' Fig. Q. The base 10 of the loch may he jfastened on the door 1.1 by screws 12, which are covered when the cover 13 of the lock is in place. A holt 14 is mounted in a suitable guidivay Miri (havin,

15 in the hase 10, and is springpressed outwardly hy e Spring 1C rlfhe holt 14 is provided with o shoulder 17 nt its inner end, which Shoulder is suitably spaced from the arm 18 of un operating lever 19 overlying the holt so that there is* just space for the desired Coin, usually u live cent piece,

v to be received edgewise hetweensuch shoulder and ami. The' coin may he dropped in from the outside of the door through u hori Zontal slot 20 in the Jfront face of the cover 13, passingr thence bv gravity through a coin Chute 21 located within thel casing formed hy the base 1G and cover 13 and having a suitably curved back to guide the Coin into the spare between the arm 18 and shoulder 017 and. holt 1:1 and cover 13. If now he turned by the knol) Q2 on the front of the lock, the shank Z3 of which lrnoh is attached to the operating lever 19 by a ser-ew '24 Within the look casA ing, the erm 1S pushes the coin edgewise, and through the coin and the shoulder 17 withdraws the holt 11' to permitthe door to he opened. .t the saine time, a projection from the lower end of the operating lever 19 upward into a notch il@ in the lower side of the holt 11, and also pushes upward a slide 27 from the position shown in Fig. Z to the position shown in Fig. 3. The pioiertion :25. after once enteringr the not-ch :2G will prevent the holt 1l from being pnzhed out hv the spring 1G it the coin for any reason should drop from between the arm 1S and shoulder 17, thereby preventing the user from losing his coin by inexpert manipulation of the lock. Moreover, the projection 25, meting against the under surf'iwe of the holt il, prevents the lcnoh from being turned at fill unless there is a Coin. hetueen the :irm 18 and the shoulder 17. The upward movement of the slide 2T oper-tes a re 'ster 230, the arm 31 of such register ittinb in a notch in the slide The slide 2l is provided with a transverse arm 33 which when the slide moves upward covers the inner side of the slot 20, :is indicated in Fig. This prevents another roin `trom being dropped in the slot while the slide in this position. Y

'When the user releases the knob the spring; 3:3 pushes it heele to normal position, und :it the suine time the spring-16 pushes the holt 11 to its normal position. During this time, the coin remains held, under ordinary Conditions, between the arm 18 and the sl'ioulder 17, 'a V.shoulder 36 on such arm preventing the coin from droppinv. This also helps to prevent loss of 'the coin by inexpert manipulation of the door. As the door is nou' closed, the holt 14 is momen tai-ily pushed inward hy the usual @am aetion of the holt on the door frame, and the coin is released und drops down into the bottom of the look Casing. When the user now"'desires to open the door fromthe '1nsidefhe turns the inside knob 40, the shank 41 of which carries :in operating lever 452 fastened/,tofsuch shank by a screw 13 Within the lock easing. The lever 42 has two iingers 111' and @15, the former cooperating with a notch 16 in the upper surface of the bolt 14 to slide such bolt inwardly, and the la.tter ooperziting with@ shoulder 47 on the slide Q7 to more said slideoaclr from the pol" sition shown in 3 to the position shown in Fig. 2, thereby returning the register arm 31 to the position from which it may again operate the register and also moving the transverse arm of the slide from its position co: ering the slot 20. As the knob l0 is now released, the spring 1G returns the bolt il to its normal outward position, and the lock is again read)y for operation by a coin.

In order to allow the lock to be. opened from the outside b v an authorized person, the cover lil is provided with a ke)Y hole 50, whereby a porters kev maiY be inserted in the hole al tor the key shank and the wards olI the ke may cot'perate with a notch on the upper surl'nce oll the holt ll to withdraw such bolt. This withdrawal ol. the bolt does not all'ect the slide 12T. 'hen the lock is operated liv thc porters key. the wards of the latter, as the turningr thereol is completed, enter a notch 533 on the edge ol' the slide 27, thus lockingy auch slide and the knol 2:2 against movement.

The cover 12S of the lock is provided with a removable panel 55 provided with a lock 5G. .ly unlocking the lock 5G and removing the panel 55, the coins which have collected within the lock casing can be removed. Beneath the panel 55, the cover 13 is provided with a pair ot lugs 5T, through which screws 5S extend into the holes of) in the hase. 10 of the lock. These screws hold the Cover 13 upon the base, and are covered when the panel 55 is in place. Since the screws 58, the screws 12, and the screws 2l and 43 are all inaccessible when the lock is in working condition, it is practically impossible for the lock tobe tampered with.

I claim as my invention:

1. rl`he combination, in a, coin-controlled lock, ol a easing, a bolt slidably mounted therein and provided with a shoulder and a notch. an operating` lever which may act to withdraw such bolt when a coin of the required denomination is deposited between the lever and said shoulder,l and a projection on said operatingv lever which swings into the notch in the holt when the bolt is witlulrawu hut which hears against a side olA the holt and prevents the turning of the operating lever unless the required coin 1s deposited.

L). The combination, in a coin-controlled lock. oi" a casing, a holt slidahly mounted therein. and provided with a notch, an 0perating lever which when a coin of the required denomination is deposited may act through said coin to withdraw the bolt, and a projection on said operating lever which swings into the notch in the bolt when the holt is withdrawn but which bears against a side ot' the holt and prevents the turning ol the operating lever unless the required coin is deposited.

ln witness whereof. l have hereunto set my hand and' seal :it Indianapolis, Indiana, this 6th day ol September, A. D. one thousand nine. lumdred and twelve.
